PRODUCT OVERVIEW
The MX41 is designed to mix the signals from four microphones and one of two music sources into two
independently controlled zone outputs.
Each of the four microphone inputs is balanced on XLR's and has a volume control and individual phantom
power switching. Microphone inputs one and two have priority over the other two inputs and the music source.
The depth and threshold of the voice-over action is set via front panel screwdriver controls.
Two music sources may be connected via rear panel phono sockets and selected by front panel push switches.
The level of the music source is controlled by a front panel volume control.
The MX41 also incorporates a two-band equaliser on front panel screwdriver controls. Main and auxiliary
outputs are balanced on XLR's with separate level controls and an LED bargraph output level meter. A separate
record output on Phono's provides a pre-fade record facility.
The operation of the MX41 has been kept simple for use by non pro-audio users in a variety of applications
such as restaurants, shops, clubs and churches.
